Question 2

The preventable monthly loss at a company has a normal distribution with a mean of 4900 and a standard deviation of 30. A new policy was put into place, and the preventable loss the next month was 4720. What inference can you make about the new policy?
 
  A) Because the probability that the monthly loss would be as low as 4720 is small, the new policy is working.
  B) While the probability that the monthly loss would be as low as 4720 is small, it is not unexpected.
  C) The new policy is probably less effective than the one it replaced.
  D) Because the probability that the monthly loss would be as low as 4720 is not very small, the new policy is not working.
